ASSOCIAÇÃO DE FUNGICIDA E SILÍCIO LÍQUIDO SOLÚVEL EM pH DE CALDA ALCALINO NO CRESCIMENTO VEGETATIVO E CONTROLE DE DOENÇAS DE DOENÇAS FOLIARES DO CAFEEIRO

The sources foliar application of silicon soluble they have been focus of several researches, for your pratice and possibility of the use of doses smaller, susceptible to use in equipments used usually by the producers. In the cafeeiro few works exist, however, the use of soluble sources as the potassium silicato presents potential in the integrated handling of diseases. Several authors that condemn the use of fungicides in high syrup pH for harming the action of the product exist, however, the representatives of the syrups are not approached with high pH. The experimental was in blocks casualizados, with 4 repetitions and 9 treatments. The treatments were constituted of the proportion of potassium silicate (Sili-K®) and fungicide (Epoxiconazole + Pyraclostrobin). The evaluations were initiate 30 days after the second application, for determination of the number of leaves for plagiotropic branch and total diseases foliate incidence (Rust, Phoma and Ascochyta and Brown Eye Spot). The association of the fungicide epoxiconazole + pyraclostrobin and silicon liquid soluble (Sili-K) it doesn't harm the control of the rust and of Phoma and Ascochyta and it improves the control of the cercosporiose of the cafeeiro indeed and it does promote larger vegetative growth in alkaline syrup pH.
